Cavity-controlled formation of ultracold molecules

open access: yesNew Journal of Physics, 2018
Ultracold ground-state molecules can be formed from ultracold atoms via photoassociation followed by a spontaneous emission process. Typically, the molecular products are distributed over a range of final states. Here, we propose to use an optical cavity

Enhancement of ultracold molecule formation by local control in the nanosecond regime

open access: yesNew Journal of Physics, 2015
We describe quantum simulations of ultracold ^87 Rb _2 molecule formation using photoassociation (PA) with nanosecond-time-scale pulses of frequency chirped light.

Sub-Natural-Linewidth Quantum Interference Features Observed in Photoassociation of a Thermal Gas [PDF]

open access: yes, 2005
By driving photoassociation transitions we form electronically excited molecules (Na$_2^*$) from ultra-cold (50-300 $\mu$K) Na atoms. Using a second laser to drive transitions from the excited state to a level in the molecular ground state, we are able ...

High-precision spectroscopy of ultracold molecules in an optical lattice

open access: yesNew Journal of Physics, 2015
The study of ultracold molecules tightly trapped in an optical lattice can expand the frontier of precision measurement and spectroscopy, and provide a deeper insight into molecular and fundamental physics.

Feshbach-resonant Raman photoassociation in a Bose-Einstein condensate

open access: yes, 2011
We model the formation of stable heteronuclear molecules via pulsed Raman photoassociation of a two-component Bose-Einstein condensate near a strong Feshbach resonance, for both counterintuitive and intuitive pulse sequencing.

A dynamical process of optically trapped singlet ground state 85Rb133Cs molecules produced via short-range photoassociation. [PDF]

open access: yesPhysical Chemistry, Chemical Physics - PCCP, 2018
We investigate the dynamical process of optically trapped X1Σ+ (v'' = 0) state 85Rb133Cs molecules distributed in J'' = 1 and J'' = 3 rotational states.

Photoassociation Spectroscopy of Laser-Cooled Ytterbium Atoms [PDF]

open access: yesPhysical Review Letters, 2004
We report the photoassociation spectroscopy of laser-cooled ytterbium atoms in an optical trap. We observed more than 90 photoassociation resonances of vibrational levels in the (1)Sigma(+)(u) state, including 80 consecutive series, up to 490 GHz detuning with respect to the atomic resonance.

Detecting high-density ultracold molecules using atom–molecule collision

open access: yesNew Journal of Physics, 2013
Utilizing single-photon photoassociation, we have achieved ultracold rubidium molecules with a high number density that provides a new efficient approach toward molecular quantum degeneracy.

Continuous production of rovibronic-ground-state RbCs molecules via short-range photoassociation to thebΠ13–cΣ1+3–BΠ11states [PDF]

open access: yesPhysical Review A, 2018
We have investigated rovibronic levels of the strongly mixed $b^3\Pi_1-c^3\Sigma^+_1-B^1\Pi_1$ states [the 2(1), 3(1), and 4(1) states in Hund's case (c) notation] of $^{85}$Rb$^{133}$Cs in the energy range of 13950$-$14200 cm$^{-1}$ using short-range ...
